Abstract. In this paper we present the DLSIAUES team’s participation in the TAC 2008 Opinion Pilot and Recognizing Textual Entailment tasks. Structured in two distinct parts corresponding to these tasks, the paper presents the opinion and textual entailment systems, their components, as well as the tools and methods used to implement the approaches taken. Moreover, we describe the difficulties encountered at different steps and the distinct solutions that were adopted. We present the results of the evaluations performed within TAC 2008, analyze them and comment upon their significance. Finally, we conclude on the performed experiments and present some of the lines for future work. Overview Three tracks were defined in this year's TAC edition (TAC 2008): Question Answering, Recognizing Textual Entailment and Summarization. The Summarization track included two tasks: the Update Summarization and the Opinion Summarization Pilot task. The DLSIUAES team participated in two of these tracks, the Recognizing Textual Entailment track and the Opinion Summarization Pilot task within the Summarization track. This paper is mainly divided into two parts with respect to the tasks in which the DLSIUAES team participated. The first part describes the two approaches taken in the Opinion Summarization Pilot task and is
