2016/12/29 - (Patent) Systems and methods for collaborative note-taking

Reading range : from [0001] to [0045]

Background of the invention

This invention relates to :

  1. Collaborative note-talking

  2. collaborative feedback

  3. dynamic learning

  4. dynamic adaptation based on collaborative feedback

Participants in classes and seminars frequently switch the focus of their attention between note taking tasks and the task of assimilating the material presnted.

Two exemplary note-taking styles :

  1. Taking detailed note but less assimilation.

  2. Less detailed note-taking but assimilating more material in presentation.

Some meeting capture ststem using automatic speech recognition.But :

  • Do not integrate the presentation material

  • Low accuracy makes a lot of recognition errors - Misdirect the user’s focus of attention

Summary of the invention

Dynamically determine language models based on domain indicactors in speech would therefore be useful.

Detailed description of exemplary embodiments

Fig.1

[0026]The speaker based language model is used to compensate for idiosyncratic(有特性的) speech characterisitcs such as the accent of the speaker, prosody, intonnation and the like.

[0029 - 0031] Domain based on language model -> Linguistic analysis using tools of Xerox Linguistic Environment (Parser)

[0032] Correctness score based on users’ feedback.

[0037] Monitored action are used to determine a collaborative user feedback signal.

Fig. 2

[0040] Speaker identifier information like wireless microphone is optional.

[0043]Sailent tokens are determined based on the imformativity of the words in the speech information. The classification of non-function words based on parts-of-speech such as adjectives , verbs , and nouns and/or references to presentation support information is used to determine the salient tokens.

My summary in this session of reading

我之前用過的共同筆記是像 Hackpad 這樣的方式，是大家有一個共同的空間，可以即時看到是誰在做筆記、看到誰正在做筆記，這篇專利看到目前為止再討論的部份似乎著重在選擇Language與Parsing 的階段，還沒有看到如何做到向Hackpad這樣即時多人共同做筆記的部份。
