Methods and systems for providing a user with content relevant to a location of interest to the user, when the user is determined to be at or near the location, are presented. The user's interest in the location may be determined based on queries about the location received from the user prior to the user arriving at the location. The queries received from the user about the location are used to build a location recommendation model, which generates personalized content relevant to the location and to one or more interest verticals identified for the user. The location recommendation model is built using a location recommendation engine that collects data about the user, the queried location, one or more associations between the user, the queried location, and/or one or more other users, as well as various other information related to the user's interests and the queried location.

An article is described comprising a first film layer comprising polylactic acid polymer (semicrystalline polylactic acid polymer; amorphous polylactic acid polymer; or a mixture thereof); a second (e.g. polyvinyl acetate) polymer having a Tg of at least 25° C.; plasticizer. In some embodiment, the film layer further comprises inorganic pigment and/or hydrolysis stabilizer. In other embodiments, the film has a net melting endotherm, ΔH.sub.nm1, of less than 10 J/g. Also described are methods of making a graphic film.
