摘要： A mechanism is provided in a data processing system for question answering using time weighted evidence. The mechanism receives an input question. The mechanism determines a time focus for the input question and defines a weighting function. The weighting function is a bell curve having a peak at the time focus on a time axis. The mechanism decomposes the input question into one or more queries and applies the one or more queries to a corpus of information to obtain a set of hypothesis evidence. Each item of information within the hypothesis evidence has an associated time value. The mechanism weights the set of hypothesis evidence based on the associated time values according to the weighting function to form time weighted evidence and generates hypotheses for answering the input question based on the time weighted evidence.

摘要： A mechanism is provided in a data processing system for question answering using context features in closure form. The mechanism receives a function call comprising an input question and a set of non-local context evidence in closure form. The mechanism decomposes the input question into one or more queries and applies the one or more queries to a corpus of information to obtain a set of local hypothesis evidence. The mechanism generates hypotheses for answering the input question based on the local hypothesis evidence and the set of non-local context evidence.
摘要翻译：在使用封闭形式的上下文特征的问题回答的数据处理系统中提供了一种机制。该机制接收包括输入问题和一组封闭形式的非局部上下文证据的函数调用。该机制将输入问题分解为一个或多个查询，并将一个或多个查询应用于信息语料库以获得一组局部假设证据。该机制基于本地假设证据和一组非本地上下文证据产生了回答输入问题的假设。
