Assessing semantic similarity of texts Methods and algorithms AIP Conference Proceedings AIP Publishing

In practice, we also have mostly linked collections, rather than just one collection used for specific tasks. Content testing of the tool should check the quality of the analysis, especially when it comes to documents describing different content areas, if the typical concepts of all areas are covered and that all related documents are searched. This paper addresses the above challenge by a model embracing both components just mentioned, namely complex-valued calculus of state representations and entanglement of quantum states. A conceptual basis necessary to this end is presented in “Neural basis of quantum cognitive modeling” section. This includes deeper grounding of quantum modeling approach in neurophysiology of human decision making proposed in45,46, and specific method for construction of the quantum state space.

You understand that a customer is frustrated because a customer service agent is taking too long to respond. In the dynamic landscape of customer service, staying ahead of the curve is not just a… To classify sentiment, we remove neutral score 3, then group score 4 and 5 to positive (1), and score 1 and 2 to negative (0). Among the three words, “peanut”, “jumbo” and “error”, tf-idf gives the highest weight to “jumbo”. This is how to use the tf-idf to indicate the importance of words or terms inside a collection of documents.

These two techniques can be used in the context of customer service to refine the comprehension of natural language and sentiment. This technology is already in use and is analysing the emotion and meaning of exchanges between humans and machines. Read on to find out more about this semantic analysis and its applications for customer service.

Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Preserving physical systems in superposition states (1) requires protection of the observable from interaction with the environment that would actualize one of the superposed potential states96. Similarly, preserving cognitive superposition means refraining from judgments or decisions demanding resolution of the considered alternative.

Cdiscount and the semantic analysis of customer reviews

Indeed, semantic analysis is pivotal, fostering better user experiences and enabling more efficient information retrieval and processing. Semantic analysis techniques involve extracting meaning from text through grammatical analysis and discerning connections between words in context. This process empowers computers to interpret words and entire passages or documents. Word sense disambiguation, a vital aspect, helps determine multiple meanings of words. This proficiency goes beyond comprehension; it drives data analysis, guides customer feedback strategies, shapes customer-centric approaches, automates processes, and deciphers unstructured text. Semantic Analysis is a subfield of Natural Language Processing (NLP) that attempts to understand the meaning of Natural Language.

Insights derived from data also help teams detect areas of improvement and make better decisions. For example, you might decide to create a strong knowledge base by identifying the most common customer inquiries. Using the tool increases efficiency when browsing through different sources that are currently unrelated. We would also like to emphasise that the search is performed among credible sources that contain reliable and relevant information, which is of paramount importance in today’s flood of information on the Internet. Latent Semantic Analysis (LSA) is a theory and method for extracting and representing the contextual-usage meaning of words by statistical computations applied to a large corpus of text.

Scaling of semantics: from the bag of words to the bag of sentences and further

Text semantics are frequently addressed in text mining studies, since it has an important influence in text meaning. This paper reported a systematic mapping study conducted to overview semantics-concerned text mining literature. Thus, due to limitations of time and resources, the mapping was mainly performed based on abstracts of papers. Nevertheless, we believe that our limitations do not have a crucial impact on the results, since our study has a broad coverage. When looking at the external knowledge sources used in semantics-concerned text mining studies (Fig. 7), WordNet is the most used source. This lexical resource is cited by 29.9% of the studies that uses information beyond the text data.

Today we will be exploring how some of the latest developments in NLP (Natural Language Processing) can make it easier for us to process and analyze text. We can any of the below two semantic analysis techniques depending on the type of information you would like to obtain from the given data. As we discussed, the most important task of semantic analysis is to find the proper meaning of the sentence. This article is part of an ongoing blog series on Natural Language Processing (NLP). I hope after reading that article you can understand the power of NLP in Artificial Intelligence.

In accord, this makes a powerful navigator in space of behavioral and linguistic models as discussed in more detail in “Discussion” section. A detailed literature review, as the review of Wimalasuriya and Dou [17] (described in “Surveys” section), would be worthy for organization and summarization of these specific research subjects. The second most used source is Wikipedia [73], which covers a wide range of subjects and has the advantage of presenting the same concept in different languages. Wikipedia concepts, as well as their links and categories, are also useful for enriching text representation [74–77] or classifying documents [78–80]. Stavrianou et al. [15] present a survey of semantic issues of text mining, which are originated from natural language particularities. This is a good survey focused on a linguistic point of view, rather than focusing only on statistics.

QuestionPro, a survey and research platform, might have certain features or functionalities that could complement or support the semantic analysis process. It recreates a crucial role in enhancing the understanding of data for machine learning models, thereby making them capable of reasoning and understanding context more effectively. It is a crucial component of Natural Language Processing (NLP) and the inspiration for applications like chatbots, search engines, and text analysis using machine learning. 1 A simple search for “systematic review” on the Scopus database in June 2016 returned, by subject area, 130,546 Health Sciences documents (125,254 of them for Medicine) and only 5,539 Physical Sciences (1328 of them for Computer Science).

• A probable reason is the difficulty inherent to an evaluation based on the user’s needs.
• Thus, as and when a new change is introduced on the Uber app, the semantic analysis algorithms start listening to social network feeds to understand whether users are happy about the update or if it needs further refinement.
• With sentiment analysis, companies can gauge user intent, evaluate their experience, and accordingly plan on how to address their problems and execute advertising or marketing campaigns.
• Therefore, it is not a proper representation for all possible text mining applications.

However, there is a lack of studies that integrate the different branches of research performed to incorporate text semantics in the text mining process. Secondary studies, such as surveys and reviews, can integrate and organize the studies that were already developed and guide future works. Search engines use semantic analysis to understand better and analyze user intent as they search for information on the web. Moreover, with the ability to capture the context of user searches, the engine can provide accurate and relevant results.

Besides, going even deeper in the interpretation of the sentences, we can understand their meaning—they are related to some takeover—and we can, for example, infer that there will be some impacts on the business environment. Also, ‘smart search‘ is another functionality that one can integrate with ecommerce search tools. The tool analyzes every user interaction with the ecommerce site to determine their intentions and thereby offers results inclined to those intentions.

Semantics can be related to a vast number of subjects, and most of them are studied in the natural language processing field. As examples of semantics-related subjects, we can mention representation of meaning, semantic parsing and interpretation, word sense disambiguation, and coreference resolution. Nevertheless, the focus of this paper is not on semantics but on semantics-concerned text mining studies. This paper aims to point some directions to the reader who is interested in semantics-concerned text mining researches. Although several researches have been developed in the text mining field, the processing of text semantics remains an open research problem. The field lacks secondary studies in areas that has a high number of primary studies, such as feature enrichment for a better text representation in the vector space model.

Moreover, while these are just a few areas where the analysis finds significant applications. Its potential reaches into numerous other domains where understanding language’s meaning and context is crucial. Semantic analysis aids search engines in comprehending user queries more effectively, consequently retrieving more relevant results by considering the meaning of words, phrases, and context. While, as humans, it is pretty simple for us to understand the meaning of textual information, it is not so in the case of machines. Thus, machines tend to represent the text in specific formats in order to interpret its meaning. This formal structure that is used to understand the meaning of a text is called meaning representation.

For the further development and practical implications of the tool, it is important that the content and form of the texts and data collections which are used for searching, are complete, updated, and credible. An appropriate support should be encouraged and provided to collection custodians to equip them to align with the needs of a digital economy. Each collection needs a custodian and a procedure for maintaining the collection on a daily basis.

So, in this part of this series, we will start our discussion on Semantic analysis, which is a level of the NLP tasks, and see all the important terminologies or concepts in this analysis. Uber strategically analyzes user sentiments by closely monitoring social networks when rolling out new app versions. This practice, known as “social listening,” involves gauging user satisfaction or dissatisfaction through social media channels.

The goal is to develop a general-purpose tool for analysing sets of textual documents. Whether using machine learning or statistical techniques, the text mining approaches are usually language independent. However, specially in the natural language processing field, annotated corpora is often required to train models in order to resolve a certain task for each specific language (semantic role labeling problem is an example). Besides, linguistic resources as semantic networks or lexical databases, which are language-specific, can be used to enrich textual data. Thus, the low number of annotated data or linguistic resources can be a bottleneck when working with another language. There are important initiatives to the development of researches for other languages, as an example, we have the ACM Transactions on Asian and Low-Resource Language Information Processing [50], an ACM journal specific for that subject.

Simplicity and interpretability of the model, in accord with the positive results reported above, exemplifies advantage of quantum approach to cognitive modeling discussed in the beginning of this section. Every day, civil servants and officials are confronted with many voluminous documents that need to be reviewed and applied according to the information requirements of a specific task. Since reviewing many documents and selecting the most relevant ones is a time-consuming task, we have developed an AI-based approach for the content-based review of large collections of texts. The approach of semantic analysis of texts and the comparison of content relatedness between individual texts in a collection allows for timesaving and the comprehensive analysis of collections.

Thus, as and when a new change is introduced on the Uber app, the semantic analysis algorithms start listening to social network feeds to understand whether users are happy about the update or if it needs further refinement. Relationship extraction is a procedure used to determine the semantic relationship between words in a text. In semantic analysis, relationships include various entities, such as an individual’s name, place, company, designation, etc. Moreover, semantic categories such as, ‘is the chairman of,’ ‘main branch located a’’, ‘stays at,’ and others connect the above entities. Apart from these vital elements, the semantic analysis also uses semiotics and collocations to understand and interpret language.

This technique is used separately or can be used along with one of the above methods to gain more valuable insights. With the help of meaning representation, we can link linguistic elements to non-linguistic elements. Both polysemy and homonymy words have the same syntax or spelling but the main difference between them is that in polysemy, the meanings of the words are related but in homonymy, the meanings of the words are not related. In the above sentence, the speaker is talking either about Lord Ram or about a person whose name is Ram. In-Text Classification, our aim is to label the text according to the insights we intend to gain from the textual data. Likewise, the word ‘rock’ may mean ‘a stone‘ or ‘a genre of music‘ – hence, the accurate meaning of the word is highly dependent upon its context and usage in the text.

It may offer functionalities to extract keywords or themes from textual responses, thereby aiding in understanding the primary topics or concepts discussed within the provided text. Indeed, discovering a chatbot capable of understanding emotional intent or a voice bot’s discerning tone might seem like a sci-fi concept. Semantic analysis, the engine behind these advancements, dives into the meaning embedded in semantic analysis of text the text, unraveling emotional nuances and intended messages. Expert.ai’s rule-based technology starts by reading all of the words within a piece of content to capture its real meaning. It then identifies the textual elements and assigns them to their logical and grammatical roles. Finally, it analyzes the surrounding text and text structure to accurately determine the proper meaning of the words in context.

Beside Slovenian language it is planned to be possible to use also with other languages and it is an open-source tool. B2B and B2C companies are not the only ones to deploy systems of semantic analysis to optimize the customer experience. Google developed its own semantic tool to improve the understanding of user searchers. The analysis of the data is automated and the customer service teams can therefore concentrate on more complex customer inquiries, which require human intervention and understanding. Further, digitised messages, received by a chatbot, on a social network or via email, can be analyzed in real-time by machines, improving employee productivity.

“Single-concept perception”, “Two-concept perception”, “Entanglement measure of semantic connection” sections describe a model of subjective text perception and semantic relation between the resulting cognitive entities. Semantics gives a deeper understanding of the text in sources such as a blog post, comments in a forum, documents, group chat applications, chatbots, etc. With lexical semantics, the study of word meanings, semantic analysis provides a deeper understanding of unstructured text.

Learning a concept apple, for example, amounts to configuring a specialized neuronal pattern that is reliably activated by appropriate complexes of visual, touch, taste, and smell signals79 and properly connected to other concepts80. This cognitive instrument allows an individual to distinguish apples from the background and use them at his or her discretion; this makes corresponding sensual information useful, i.e. meaningful for a subject81,82,83,84. Registry of such meaningful, or semantic, distinctions, usually expressed in natural language, constitutes a basis for cognition of living systems85,86. Alternatives of each semantic distinction correspond to the alternative (eigen)states of the corresponding basis observables in quantum modeling introduced above. In “Experimental testing” section the model is approbated in its ability to simulate human judgment of semantic connection between words of natural language. Positive results obtained on a limited corpus of documents indicate potential of the developed theory for semantic analysis of natural language.

Bos [31] indicates machine learning, knowledge resources, and scaling inference as topics that can have a big impact on computational semantics in the future. Semantic analysis is defined as a process of understanding natural language (text) by extracting insightful information such as context, emotions, and sentiments from unstructured data. This article explains the fundamentals of semantic analysis, how it works, examples, and the top five semantic analysis applications in 2022. Thanks to machine learning and natural language processing (NLP), semantic analysis includes the work of reading and sorting relevant interpretations. Artificial intelligence contributes to providing better solutions to customers when they contact customer service.

We will calculate the Chi square scores for all the features and visualize the top 20, here terms or words or N-grams are features, and positive and negative are two classes. Given a feature X, we can use Chi square test to evaluate its importance to distinguish the class. I will show you how straightforward it is to conduct Chi square test based feature selection on our large scale data set. In reference to the above sentence, we can check out tf-idf scores for a few words within this sentence.

Besides that, users are also requested to manually annotate or provide a few labeled data [166, 167] or generate of hand-crafted rules [168, 169]. Besides the vector space model, there are text representations based on networks (or graphs), which can make use of some text semantic features. Network-based representations, such as bipartite networks and co-occurrence networks, can represent relationships between terms or between documents, which is not possible through the vector space model [147, 156–158].
