Abstract: A spunbond nonwoven fabric includes hollow polymeric multicomponent fibers. The spunbond nonwoven fabric has a thickness of at least 1 mm. The thickness of the spunbond nonwoven fabric is according to DIN EN ISO 9073-2:1997-02. The spunbond nonwoven fabric may have a thickness according to DIN 9073-2/1997 in the range of 1 to 25 mm.

Abstract: Tools and techniques are described for analyzing interactions to identify dissimilar items that may contain synonyms. Methods described herein may retrieve activity records that represent interactions between a visitor and a server-based system, and may identify within the activity records inputs that the visitor provided during the interaction. The methods may identify items within the activity record that are associated with the inputs, and may access additional activity records that also contain the same inputs. The methods may then identify additional items within the additional activity records that are associated with this same input, and may establish similarity ratings for the two items, with the similarity ratings indicating a likelihood that documents respectively associated with the items contain synonyms.

Abstract: Collaborative structured tagging enables a community of users to define different types of tags for online content. The diverse tag types provide a non-flat or dimensional tagging data structure that supports navigation and search for content, as well as comparison of the content. In one implementation, the collaborative structured tagging is employed in an item encyclopedia that offers community-authored information on various items in one or more electronic catalogs. In this context, the collaborative structured tagging facilitates comprehensive cross-product comparison and dimensional product navigation.
