Due to the feature and difficulty of Chinese natural language processing and the lack of related resources, some foreign mature techniques can not be applied in Chinese Question Answering (QA) system. For the Chinese factoid QA system, a new answer extraction method based on syntax structure feature parsing and classification is presented in this paper. With the method, the answer extraction is regarded as candidate answer classification problem, i.e. candidate answers are classified into correct and incorrect answer. According to the part-of-speech information of candidate answers corresponding to question types, the candidate answers and their features (both simple and syntactic) in sentences from snippets are firstly extracted. Then these features are used to train the classifier. Finally, the trained classifier is used to distinguish whether the candidate answer is correct or not. For Chinese factoid questions, comparing to currently typical pattern matching based answer extraction algorithm, the new method improves precision by 6.2% and MRR by 9.7%.
In this paper, a novel variable rate based time frame scheduling scheme is proposed to further reduce collisions and improve energy saving in wireless sensor networks. The MAC combines CSMA and TDMA functionalities, w...

This paper consists of two parts. In part one;we give a new reference definition for service, based on some fundamental concepts in economics such as homo economics and utility. Part two is primarily concerned with a service description framework, which includes the service provider, service receiver, service content, service medium and service environment, together with some examples.

Since the establishment of the Unified Modeling Language (UML) as a standard graphical notation for representing knowledge, new ideas have emerged about tools that can automatically extract knowledge from text and represent it with UML diagrams. As the targeted representation of knowledge is in a graphical notation, we propose to also represent Natural Language (NL) and the knowledge it carries in a common graphical form, and then translate this Graphical NL (GNL) into another graphical form (UML).
Still, requirements and software design are often confused with one another. We provide a new (partial) explanation for this phenomenon, based on the insight that representations of concepts related to requirements an...

In recent years a huge number of online auctions that use Multi Agent systems have been created. As a result there are numerous auctions that provide the same product. In this case each customer can buy a product with the lowest possible price. But searching between auctions in terms of finding the suitable product can be time consuming for consumers and also providing products in different markets is a difficult task for suppliers. So the need for an autonomous agent in these types of markets is deeply felt. On the other side the structure of an auction mechanism that provides the environment for traders to operate their trades is vital. Despite all the research that has been done about online auctions, most of them were about single markets. But in real world the stocks and commodities of companies are listed and traded in different markets. There is a growing tendency towards research about online auctions and Market Design. Particularly in recent years CAT (CATallactics) game has provided an important opportunity to develop and test new techniques in this field. In this paper after introducing CAT game and PersianCAT agent, we want to challenge the conventional accepting policy used in stock markets like New York Stock Exchange and provide a better solution that improves the general performance of the markets.
