In this paper, we investigate interaction elements of query formulation-including query suggestion algorithms-for children. This calls for the examination of existing technologies in this area, to better understand what remains to be done when it comes to facilitating query-formulation tasks for young users. Moreover, even though search tools offer support to help in query formulation, these too are aimed at adults and may hinder children rather than help them. Because children have different developmental needs than adults, these tools may not always adequately support their search for information. The article also discusses some potential benefits of mind mapping for searching.Ĭhildren use popular web search tools, which are generally designed for adult users. However, this could be due to the search setting where the mind map had to be used as a separate tool and not an integrated component of the search system. Participants were happier with their search session when not using mind maps mind map might help information need clarification, but it is a barrier to interaction and serendipity retrieval.
The results revealed no statistically significant difference between searching with a mind map and without a mind map, and therefore, no advantage could be found for using a mind map in the search process. Two simulated search tasks were completed by participants in two search sessions. The study examined graduate students’ Internet information searching.
Inspired by the function of the mind in handling a situation, this article reports on an empirical study that evaluated the efficiency of mind map techniques and tools in formulating and refining information needs.

In July, the company said it had developed an AI model that can translate 200 different languages, and that one of its AI models can automatically verify hundreds of thousands of Wikipedia citations at once.ġ0 things you need to know direct to your inbox every weekday. Meta has been looking at AI as a means to improve communication in various ways. “I take this more as a proof of principle that there may be pretty rich representations in these signals – more than perhaps we would have thought,” King told Time. The company described the work as a “first step” as enabling patient communication will require extending the work to speech production. Meta said the work is a part of a “broader effort by the scientific community” to use AI to better understand the human brain. “The other big problem is more conceptual in that we actually don’t know how the brain represents language to a large extent.” So picking them up with a sensor requires super advanced technology. “There is a skull, there is skin, which can corrupt the signal that we can pick up. “The sensors are pretty far away from the brain,” King said. Jean-Rémi King, a researcher in Meta’s Brain and AI group, told Time that a number of challenges were found in the study, including the fact brain signals are “noisy”. The research is still in its early stages, however. The Meta researchers said that from three seconds of brain activity, the AI model was able to decode corresponding speech segments with up to 73pc “top-10 accuracy” from a vocabulary of 793 words. The brain activity of these volunteers was captured using electro and magnetoencephalography, which are non-invasive ways to record brain activity. In the pre-print study, researchers tested the AI model on four public datasets, which consisted of 169 volunteers listening to audiobooks and isolated sentences in English and Dutch. The parent company of Facebook said this is a “long-awaited goal” in both healthcare and neuroscience, as it could improve the lives of those with brain injuries that make them unable to communicate through speech, typing or gestures. In an ambitious study, which has not been peer reviewed, Meta scientists sought to decode speech from non-invasive brain recordings using an AI model.
New exploratory research at Meta is looking at ways to understand what’s happening in people’s minds using AI. In a pre-print study, Meta scientists said their AI model was able to decode speech segmengs from three seconds of brain activity.
