Our next Swiss Analytics Event, June 18th 6pm in Lausanne, is about text mining. Here is the program:
Tailor-made vs. off-the-shelf – A simple method for personalization in information retrieval (Melanie Imhof)
Abstract: The ever-increasing amount of unstructured data makes it not only difficult to find relevant information but also to formulate specific, non-ambiguous queries. Information retrieval systems generally apply the “one size fits all” paradigm, where for the same query submitted by different users the same result list is returned. Personalization aims to overcome this limitation and hence to increase the effectiveness of retrieval by tailoring to individual users’ interests. We will outline a personalization approach based on relevance feedback and query expansion. The key idea of the approach is to infer the future interests of a user based on his past interactions with the system. We will demonstrate how we successfully applied the approach in several projects with industry partners.
Telling Stories Through Keywords in Document Clusters (Periklis Andritsos)
Abstract: This presentation will showcase how from clustered information we can unleash the power of their keywords. Through a simple, yet powerful expression of the information content of keywords, we will show how thousands of unstructured documents can speak. We will present an experiment that was performed with real news stories taken from an online aggregator of news. Our goal is to provide insights into why clusters of such stories are built and, through that, simplify the role of the reader to decipher the content inside them.
Helping companies make the most of their content with NLP (Silvia Quarteroni + Jérôme Berthier)
Abstract: Natural Language Processing is a 50-year-old discipline that was traditionally confined to very specific industrial/defense applications. Nowadays, thanks to the success of flagship technologies such as question answering (IBM Watson), speech recognition and understanding (Siri), sentiment analysis (especially on Twitter) and “semantic” search (Google), NLP is gaining more and more interest from the market. This talk will present a selection of projects where NLP is applied to the concrete problems of ELCA’s customers. Our results indicate that NLP is now a mature technology, offering effective solutions and measurable results in many different industry domains.
