Domain hierarchies are widely used as models underlying information retrieval tasks. Formal ontologies and taxonomies enrich such hierarchies further with properties and relationships associated with concepts and categories but require manual effort; therefore they are costly to maintain, and often stale. Folksonomies and vocabularies lack rich category structure and are almost entirely devoid ...

Negotiation is essential in settings where computational agents have conflicting interests and a desire to cooperate. Mechanisms in which agents exchange potential agreements according to various rules of interaction have become very popular in recent years as evident, for example, in the auction and mechanism design community. These can be seen as models of negotiation in which participants fo...

This review summarizes about the actinobacteria and their capability to produce bioactive secondary metabolites. Actinobacteria are of special biotechnological interest since they are known to produce chemically diverse compounds with a wide range of biological activity. This distinct clade of Gram-positve bacteria include some of the key antibiotic producers and are also sources of several bio...

The Society has several Special Interest Groups which organise meetings and other activities to enable the exchange of information and views within specific areas of meteorology. These are informal groups of professionals interested in specific technical areas of meteorology. The groups are primarily a way of communicating at a specialist level and are organized and often financed by the group ...

This study describes and reconciles two common, seemingly contradictory views about a key monetary policy relationship: that between money and interest rates. Data since 1960 for about 40 countries support the Fisher equation view, that these variables are positively related. But studies taking expectations into account support the liquidity effect view, that they are negatively related. A simp...

In the rapidly evolving and growing environment of the internet, website owners aim to maximize interest for their website. In this article we propose a model, which combines the static structure of the internet with activity based data, to compute a website interest ranking. This ranking can be used to gain more insight into the flow of users over the internet, optimize the position of a websi...

Explaining the maintenance of communicative behavior in the face of incentives to deceive, conceal information, or exaggerate is an important problem in behavioral biology. When the interests of agents diverge, some form of signal cost is often seen as essential to maintaining honesty. Here, novel computational methods are used to investigate the role of common interest between the sender and r...
