  • System Introduction
zoom OrientSpace is a PIM (Personal Information Management) prototype system built in the objective of resolving rising challenges of personal data management. We aim at offering more comfortable and easy-to-use data management experience to users. As the first beta edition of OrientSpace, we would like to address the following 3 features:

Search your data by content-based associations

Explore your data space through content-based associations when you don't what keyword search to issue.

Manage evolving data in flexible schema

Free to create and modify data schemas to meet evolving data information.

Locate important data quickly using CoreSpace

Leverage CoreSpace to find your frequently accessed important files quickly.


Besides the 3 features above, OrientSpace also provides a simple Resource Manager similar to that in the Windows OS to lessen the switch between OrientSpace and the file system.



Detailed introduction

  • Search your data by content-based associations


    Most PIM applications allow users to issue keyword search to in order to find their desired files, but there're occasions when users don't remember the exact content of the file or don't know what keyword to input.

    If you unfortunately run into these situations, OrientSpace can help you with content-based associations among files. You can first using keyword search to search for some files that you think are related to the desired file, and then leveraging the content-based associations to browse files that are related to the search results. And in the related files you may find your desired file, and if not, you can repeat this   process   until   succeed. [Example]

  • Manage evolving data in flexible schema


    One of the challenges of PIM nowadays is that the schemas of data are sometimes evolving over time. For instance, you may keep get new information about a person, but the attributes of contact in outlook never change, so you have to find other ways.

    In OrientSpace, we enable users to manage their data schema in a very flexible way. Users can create and modify data schemas as they wish in a lightweight way. Typically, when you get a piece of new information about something, you can add a new attribute and insert the new information. And the new attribute is added to the schema, so later insertion of data can see this new attribute. [Example]

  • Locate important data quickly using CoreSpace


    Nowadays each person has a lot of documents in their computer, but among which only a fraction of files are important to users for a certain period. By important, we mean this file is frequently accessed by the user recently and therefore is of more importance to the user than others.

    We implemented an algorithm to build the CoreSpace of users' whole data space in the hope of recording the most important files so that users can quickly find their frequently used files in no time. [Example]
