Collaborative filtering: In the newer, narrower sense, collaborative filtering is a method of making automatic predictions (filtering) about the interests of a user by collecting preferences or taste information from many users (collaborating).  The underlying assumption of the collaborative filtering approach is that if a person "A" has the same opinion as a person "B" on an issue, A is more likely to have B's opinion on a different issue than that of a randomly chosen person.  For example, a collaborative filtering recommendation system for television tastes could make predictions about which television show a user should like given a partial list of that user's tastes (likes or dislikes).  Note that these predictions are specific to the user, but use information gleaned from many users.  This differs from the simpler approach of giving an average (non-specific) score for each item of interest, for example based on its number of votes.

Sing Date: Sing Date unofficially billed as dating by music is a TV series which started in summer 2012 on Sky Living in the UK where contestants get to go for a date having chosen a person to date from a list of videos of people singing.  They then go on a date and at the end of the date they enter a studio and sing the same song together - hopefully in tune.  It is too soon to tell whether any long term relationships will come out of this however.  The programme's voiceover comes from actress Sally Lindsay.

Phraseme: A phraseme, also called a set of thoughts, set phrase, idiomatic phrase, multi-word expression (in computational linguistics), or idiom, is a multi-word or multi-morphemic utterance at least one of whose components is selectionally constrained or restricted by linguistic convention such that it is not freely chosen.  In the most extreme cases, there are expressions such as "X kicks the bucket" ≈ ‘person X dies of natural causes, the speaker being flippant about X’s demise’ where the unit is selected as a whole to express a meaning that bears little or no relation to the meanings of its parts.  All of the words in this expression are chosen restrictedly, as part of a chunk.  At the other extreme, there are collocations such as "stark naked", "hearty laugh", or "infinite patience" where one of the words is chosen freely ("naked", "laugh", and "patience", respectively) based on the meaning the speaker wishes to express while the choice of the other (intensifying) word ("stark", "hearty", "infinite") is constrained by the conventions of the English language (hence, *"hearty naked", *"infinite laugh", *"stark patience").  Both kinds of expression are phrasemes, and can be contrasted with ’’free phrases’’, expressions where all of the members (barring grammatical elements whose choice is forced by the morphosyntax of the language) are chosen freely, based exclusively on their meaning and the message that the speaker wishes to communicate.
