dc.description.abstract | Textual conversations on the Internet, such us chat rooms or instant messaging services, have become an excellent source of data for semantic analysis. In particular, potential user interests or user-related topics could be extracted from these conversations for personalization purposes. In this work, we present a novel method for topic detection from chat logs. First, we de ned the generic structure of the process. Then, a variety of text-mining techniques was evaluated in each step of the process. Stemming, synonyms, POS tagging and named entities recognition are examples of these techniques. Encouraging experimental results from a comparative evaluation procedure, allow us to determine the most suitable combination of techniques for the problem. | en |
