말뭉치

1. Topic modeling is a frequently used text-mining tool for discovery of hidden semantic structures in a text body.
2. The "topics" produced by topic modeling techniques are clusters of similar words.
3. Yang, Torget and Mihalcea applied topic modeling methods to newspapers from 1829–2008.
4. With this, we come to this end of tutorial on Topic Modeling.
5. Topic Modeling is a technique to extract the hidden topics from large volumes of text.
6. LDA’s approach to topic modeling is it considers each document as a collection of topics in a certain proportion.
7. We started with understanding what topic modeling can do.
8. with topic modeling, we can easily understand, organize, and summarize a large collection of textual information.
9. With this open-source tool, the repetitive process in topic modeling can be done at the click of a button or selection of an action bar without the need to do any coding.
10. In this guide, we’re going to take a look at two types of topic analysis techniques: topic modeling and topic classification.
11. Topic modeling is an ‘unsupervised’ machine learning technique, in other words, one that doesn’t require training.
12. First, we’ll delve into what topic modeling is, how it works, and how it compares to topic classification.
13. Topic modeling is a machine learning technique that automatically analyzes text data to determine cluster words for a set of documents.
14. As a result, the goal of topic modeling is to uncover these latent variables — topics — that shape the meaning of our document and corpus.
15. Topic modeling is a type of statistical modeling for discovering the abstract “topics” that occur in a collection of documents.
16. Depending on your choice of python notebook, you are going to need to install and load the following packages to perform topic modeling.
17. We’ve covered some cutting-edge topic modeling approaches in this post.
18. In topic modeling, we are mining a large collection of text.
19. What evidence do we have that search engine algorithms use topic modeling, apart from the obvious usefulness of topic modeling?
20. Select a topic modeling program.
21. Whether or not you utilize topic modeling in your search engine marketing campaign will depend largely on the level of sophistication of your search engine marketing team.
22. In our proposed method, clustering-based semantic similarity topic modeling is used in order to summarize the clinical reports based on latent Dirichlet allocation (LDA) in a MapReduce framework.
23. This paper investigates the topic modeling subject and its common application areas, methods, and tools.
24. Also, we examine and compare five frequently used topic modeling methods, as applied to short textual social data, to show their benefits practically in detecting important topics.
25. In this paper, we focused on the topic modeling (TM) task, which was described by Miriam (2012) as a method to find groups of words (topics) in a corpus of text.
26. In Section Proposed Topic Modeling Methodology, we focus on five TM methods proposed in our study besides our evaluation process and its results.
27. Topic modeling has been commonly used to discover topics from document collections.
28. W PMLR %X Topic modeling has been commonly used to discover topics from document collections.
29. Topic Modeling using Topics from Many Domains, Lifelong Learning and Big Data.
30. We wanted to highlight some from our most recent How to Use Topic Modeling to Extract Conversational Insights.
31. How is topic modeling different from categories themselves?
32. But in practice, you will likely combine topic modeling and classification models because the outcome from topic modeling is the input classification.
33. You can use classification to verify whether the topic modeling technique makes business sense.
34. As Figure 6.1 shows, we can use tidy text principles to approach topic modeling with the same set of tidy tools we’ve used throughout this book.
35. For example, we could collect a set of documents that definitely relate to four separate topics, then perform topic modeling to see whether the algorithm can correctly distinguish the four groups.
36. Each debate has multiple turns (a single uninterrupted speech by a unique congressperson), and we use each turn as a document for topic modeling.
37. This is to avoid experimental differences caused by the experimental group benefiting from exploring the corpus rather than from interactive topic modeling.
38. Using this information, we compute the variation of information (Meilă 2007) between the true labels and the topic modeling clusters.
39. This study provides evidence that the itm interface assists users in exploring a large corpus and that topic modeling is helpful for users attempting to understand legislative documents.
40. This essence of topic modeling strongly accords with biologists’ interests, which include discovering latent patterns in massive biological data.
41. Hence, in recent years, extensive studies have been conducted in the area of biological-data topic modeling.
42. As discussed in “Topic modeling” section the learning process of an LDA model is completely unsupervised; hence, its research area is currently concentrated on unlabeled data.
43. In this section, several examples of related articles will illustrate this kind of research, which predominates in the use of biological-data topic modeling.
