Text analysis in the social sciences by Laura Castro-Schilo

Such “sense embedding” vectors are studied in Chen, Liu, and Sun (Reference Chen, Liu and Sun2014), where the authors emphasize the weaknesses of distributional, cluster-based models like the ones in Huang et al. (Reference Huang, Socher, Manning and Ng2012). Instead, they use skip-gram initialized word embeddings, aggregated to sense-level vectors by combining synset definition word vectors from WordNet. Word sense disambiguation (WSD) is performed via a context vector, with strategies based on word order or candidate sense set size, for each ambiguous word.

In Section 4.1, we describe the datasets and the experimental setup, in Section 4.2, we present and discuss the obtained results, and in Section 4.3, we compare our approach to related studies. To ensure adequate word context for generating representative semantic embeddings, we discard all synsets with fewer than 25 context words. The synset vector computation process from the whole WordNet, which is illustrated in Figure 4, results in 753 adequately represented synsets.

It is particularly important in the case of homonyms, i.e. words which sound the same but have different meanings. For example, when we say “I listen to rock music” in English, we know very well that ‘rock’ here means a musical genre, not a mineral material. Leser and Hakenberg [25] presents a survey of biomedical named entity recognition. The authors present the difficulties of both identifying entities (like genes, proteins, and diseases) and evaluating named entity recognition systems.

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. These chatbots act as semantic analysis tools that are enabled with keyword recognition and conversational capabilities. These tools help resolve customer problems in minimal time, thereby increasing customer satisfaction. Semantic analysis methods will provide companies the ability to understand the meaning of the text and achieve comprehension and communication levels that are at par with humans.

The accuracy of the summary depends on a machine’s ability to understand language data. In the social sciences, textual analysis is often applied to texts such as interview transcripts and surveys, as well as to various types of media. Social scientists use textual data to draw empirical conclusions about social relations. QuestionPro, a survey and research platform, might have certain features or functionalities that could complement or support the semantic analysis process.

The authors also discuss some existing text representation approaches in terms of features, representation model, and application task. The set of different approaches to measure the similarity between documents is also presented, categorizing the similarity measures by type (statistical or semantic) and by unit (words, phrases, vectors, or hierarchies). The approach in Pilehvar et al. (Reference Pilehvar, Camacho-Collados, semantic text analysis Navigli and Collier2017) examines the effect of sense and supersense information on text classification and polarity detection tasks. Disambiguation is performed by mapping the input sentence into a subgraph of the semantic resource containing all semantic candidates per word. Then, the sense with the highest node degree is picked for each word, discarding the rest and pruning the subgraph accordingly.

It often also explores potentially unintended connections between different texts, asks what a text reveals about the context in which it was written, or seeks to analyze a classic text in a new and unexpected way. Textual analysis in this context is usually creative and qualitative in its approach. Researchers seek to illuminate something about the underlying politics or social context of the cultural object they’re investigating. Moreover, QuestionPro typically provides visualization tools and reporting features to present survey data, including textual responses. These visualizations help identify trends or patterns within the unstructured text data, supporting the interpretation of semantic aspects to some extent.

  • The semantic analysis process begins by studying and analyzing the dictionary definitions and meanings of individual words also referred to as lexical semantics.
  • In-Text Classification, our aim is to label the text according to the insights we intend to gain from the textual data.
  • This proficiency goes beyond comprehension; it drives data analysis, guides customer feedback strategies, shapes customer-centric approaches, automates processes, and deciphers unstructured text.
  • Semiotics refers to what the word means and also the meaning it evokes or communicates.
  • This fact is not unexpected, since life sciences have a long time concern about standardization of vocabularies and taxonomies.
