Abstract: A server is disclosed for computing a score of an opinion that a message in a text file is expected to convey regarding a subject to be evaluated, wherein the message is written using literal strings and pictorial symbols. In this server, by the use of a pictorial-symbol dictionary memory storing a correspondence between designated pictorial-symbols to be rated and scores of opinions expressed by the respective pictorial-symbols, at least one of the used pictorial-symbols in the message which is coincident with at least one of the designated pictorial-symbols stored in the pictorial-symbol dictionary memory, is extracted from the message, at least one of the opinion scores which corresponds to the at least one extracted pictorial-symbol is retrieved within the pictorial-symbol dictionary memory, and an aggregate net opinion score for the message is calculated, based on an aggregate opinion score for the at least one extracted pictorial-symbol.

Abstract: A de-centralized, or distributed, monitoring system provides for data collection across a broad range of remote sources, collecting explicit data (which may be input directly by a user in the form of recommendation, comment, or vote) and/or implicit data (which may be collected by the system according to the user's browsing activity). Data may be monitored locally at the client side, and subsequently transmitted to a central database. Data may be aggregated at the server, having been collected on the client side from multiple remote sources. During the aggregation process, data collected by the distributed monitoring system are categorized and organized in a central database for convenient retrieval. Implementation of the collected data includes both transmitting explicit data on demand as well as utilizing explicit data, implicit data, or a combination of both explicit and implicit data, in an open recommendation system which facilitates customization and personalization of the information retrieval process.
