Abstract: A device, system and process for controlling document access using hierarchical paths is provided. A query, received from a requesting device, comprises: a search string for searching a document database; and an identifier associated with a user. A security permissions database is accessed using the identifier to receive permissible hierarchical document access paths indicating document access permissions associated with the identifier. A modified query includes the permissible hierarchical document access paths. The modified query used to access an index of the document database, the index comprising: a searchable content portion, and corresponding hierarchical document access paths, of a document. Document identifiers are received that identify only the documents having: respective searchable content portions that include the search string of the modified query; and at least one respective corresponding hierarchical document access path encompassed by the permissible hierarchical document access paths.

Abstract: An RFID-based item tracking system may use statistical methods to determine whether a tag or tagged item that does not respond when inventoried is present in a particular zone or reader antenna field-of-view. In one embodiment, the item tracking system may determine an observability of an item based on one or more initial trials. Upon not detecting the item in one or more subsequent trials, the item tracking system may estimate whether the item is still present based on the observability.

Abstract: A politeness manager estimates traffic to the sites based on historical log data generated and sent by plug-ins or toolbars on client web browsers. The historical log data details dates and times the web browsers visit different web sites that is used to understand what timeframes specific web sites are busy and what timeframes the web sites are not busy. Crawl rates for different timeframes for a web site are determined based on the historical log data, and web crawlers are scheduled to crawl the web site according to the crawl rates to minimize the chances that web crawler requests are responsible for the site crashing.
