Given the huge amount of data available over the Web nowadays, search engines become essential tools helping users to find the information they are looking for. Nonetheless, search engines often return large sets of results which must be filtered by the users to find the suitable information items. However, in many cases, filtering is not enough, as the results returned by the engine require users to perform a secondary search to complement the current information thus featuring ancillary search tasks. Such ancillary search tasks create a nested context for user tasks that increases the articulatory distance between the users and their ultimate goal. In this paper, we analyze the interplay between such ancillary searches and other primary search tasks on the Web. Moreover, we describe the inside-in approach, which aims at reducing the articulatory distance between interleaved tasks by allowing users to perform ancillary search tasks without losing the context. The inside-in approach is illustrated by means of a case study based on ancillary searches of coauthors in a digital library, using an information visualization technique.

The Goals Approach: Enterprise Model-Driven Agile Human-Centered Software Engineering

“…We also apply the principle that an Actor (a User) never carries on two UTs consecutively and separately, which is a restriction that aims user performance and software development efficiency, in order to induce the reduction of the articulatory distance of the UT i.e. the user's effort [15], and suggest that the necessary tools should be provided using as little User Interface implementation space as possible. If two UTs are consecutive, then they can be merged in a single sequence of acts, expressed by a single UT, leading to is completion in the same way.…”

From Search Engines to Augmented Search Services: An End-User Development Approach

“…Several works have contributed in different aspects: scraping, semantic search, collaborative search, etc. In spite of that, a deeper understanding of ancillary searches was recently made [2], something really relevant at the moment of taking decisions.…”

“…Being able to mouse-select elements in the primary window to launch in-context searches is a means to support search start and information chaining activities. When the results are displayed in overlay mode, these connections become explicit and persistent, as it is pointed in [2]. However, although [2] motivates the need of an inside-in search approach, the proposed system is not oriented to end-users, but that it retrieves results from a single broker that is integrated by predefined databases.…”

Bridging Enterprise and Software Engineering Through an User-Centered Design Perspective

“…This aims Business Process clarification, user performance and software conception efficiency in order to deploy the necessary tools for the execution of the task by reducing articulatory distance and therefore, the user effort [15]. Hence, Goals considers any consecutive DEMO C-Acts {request (rq), promise (pm), state (st) and accept (ac)] as a single UT.…”
