This paper provides the general construetion of the optimal strategies in a special class of zero sum games with incomplete information, those in which the players move sequentially. It is shown that at any point of the game tree, a player's optimal behavioral strategy may be derived from a state variable involving two components: the first one keeps track of the information he revealed, the se...

In this paper we present an overview of the system used by the GE/Penn team for the the Question Answering Track of TREC-8. Our system uses a simple sentence ranking method which is enhanced by the addition of coreference annotated data as its input. We will present an overview of our initial system and its components. Since this was the rst time this track has been run, we made numerous additi...

This article outlines our participation in the Question Answering Track of the Text REtrieval Conference organised by the National Institute of Standards and Technology. This was our second year in the track and we hoped to improve our performance relative to 2002. In the next section we outline the general strategy we adopted, the changes relative to last year and the approaches taken to the t...

We describe a novel framework for group tracking and identiication termed ow conservation group tracking. Our framework integrates local kinematic measurements with ow conservation constraints so as to yield a robust estimation of the positions and types of targets across an arena. The framework is based on three components each of which is novel. The measurement-to-track component uses a reduc...

Friction stir lap welding (FSLW) raises the possibility of fabricating high-performance aluminum components at low cost and high efficiency. In this study, we mainly applied FSLW to fabricate multi-track 2024 aluminum alloy without using tool tilt angle, which is important for obtaining defect-free joint but significantly increases equipment cost. Firstly, systematic single-track FSLW experimen...

one of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. this is addressed in this research...

The aim of this study is to design the excellence in Mobarakeh Steel Company's strategic knowledge management. To achieve this goal, the researcher has used qualitative and quantitative methods. Therefore, the research method is the mixed one. This study, based on the nature of the data and data collection procedure, is a descriptive, exploratory research. It follows and applies development obj...

This paper describes the IBM systems for the Trilingual Entity Discovery and Linking (EDL) for the TAC 2015 KnowledgeBase Population track. The entity discovery or mention detection (MD) system is based on system combination of deep neural networks and conditional random fields. The entity linking (EL) system is based on a language independent probabilistic disambiguation model. The same EL mod...

The Data Track is a transparency-enhancing tool that aims to educate users by providing them with an overview of all their data disclosures. In this paper, we describe a cryptographic scheme for storing all data disclosures tracked by the Data Track centrally in the cloud in a privacy-friendly way. Our scheme allows users to store their data anonymously, while keeping the cloud provider account...

We describe our participation in the INEX 2008 Entity Ranking track. We develop a generative language modeling approach for the entity ranking and list completion tasks. Our framework comprises the following components: (i) entity and (ii) query language models, (iii) entity prior, (iv) the probability of an entity for a given category, and (v) the probability of an entity given another entity....
