The SEASR Team will participate in University of Victoria’s Digital Humanities Summer Institute on June 7-11, 2010. You can find information at The course entitled “SEASR in Action: Data Analytics for Humanities Scholar” will be taught by Loretta Auvil and Boris Capitanu.

The course will provide an introduction to the SEASR analytics with hands-on training with the tools.

We created a movie that highlights some of the projects and groups using the SEASR technology. Check out for more details. We will plan to update this movie periodically. If you are using SEASR, please let us know, so that we can incorporate your work.

Meandre 1.4.7 was released today, November 3, 2009. This is the last and most stable release in the 1.4 series before we move onto big changes for the 1.5 series. Version 1.4.7 has a few new features and numerous bug fixes and usability improvements.

As usual, the Download page now points to this stable release:

The raw artifacts are available at the SEASR repository:

Visible changes since 1.4.5 (Version 1.4.6 was an internal release):

* Meandre server can now load flows from the network and then be restarted and run offline.

* Improvements to the Meandre Administrative Interface for user accounts.

* Allow specification of the port when running a flow from the ZigZag console.

* Performance improvement on component installation by using MD5 checksums to check whether a particular resource already exist on the meandre server.

* When regenerating, downloading jar files is skipped if they already exist on the meandre server.

* Bug fixes.

Loretta Auvil of the SEASR Team presented an overview of SEASR at the Digital Humanities 101: Rethinking the Scholarly Enterprise Workshop at University of North Caroloina, Charlotte. The workshop was held by the Center for Humanities, Technology and Science on Friday, Oct. 9, 2009.

This workshop introduced faculty members to new research tools and approaches as well as funding opportunities available through the field of digital humanities. Guest speakers included Loretta Auvil, director of Software Environment for the Advancement of Scholarly Research; Kurt Fendt, director of HyperStudio at the Massachusetts Institute of Technology; Jason Rhody, project officer with the Office of Digital Humanities at the National Endowment for the Humanities; and Stan Ruecker, co-director of the Humanities Computing program at the University of Edmonton.

The presentation slides for SEASR can be found here.

Last night, I created a movie that walks through the process of installing the SEASR/Meandre tools and shows how to run the tools. You can check out the movie at If you listen closely you might even hear my puppy squeak a toy.

Loretta Auvil of the SEASR Team participated in a workshop at Colorado Learning and Teaching with Technology Conference (COLTT) at the University of Boulder on August 13, 2009. The workshop focused on the SEASR Analytics for Zotero, but also introduced the use of SEASR analytics for researchers data.

Loretta Auvil of the SEASR Team will be participating in a workshop at Colorado Learning and Teaching with Technology Conference (COLTT). The workshop takes place at the University of Boulder on August 13, 2009 from 1:30-3:45pm. The workshop will focus on SEASR Analytics for Zotero. You can register for the event at the COLTT website above.

This presentation will highlight the integration of two powerful tools–Zotero for data management and SEASR for analytics. Zotero was developed at the Center for History and New Media, George Mason University, and is a tool aimed at facilitating a user’s research process by providing mechanisms for collecting, managing, and citing Internet resources (websites, articles, books, etc.). Zotero functions as an extension of the popular open-source browser Firefox. One of the key features provided by Zotero is the ability to automatically extract metadata from online resources as part of the resource collection process and to store it conveniently. Zotero also provides advanced tagging and searching functionality, allowing the user to organize, find, and visualize the collected resources effortlessly.

SEASR provides a semantic-enabled web-driven dataflow-execution environment that allows others to create their own analytical components. The initial analytics are meant to be demonstrations to show capabilities such as tag cloud generation, sentence summarization, entity extraction, and citation network analysis of the selected data assets. Additional text analysis capabilities are forthcoming. SEASR provides analytics to enhance scholars’ use of digital materials by helping them uncover hidden information and connections, supporting the study of assets from small patterns drawn from a single text or chunk of text to broader entity categories and relations across a million words or a million books. These analytics are also provided as a Firefox extension. This application allows researchers to use the SEASR analytical tools with their Zotero assets in a straightforward way.

Bernie Ács of the SEASR Team made a remote presentation for the NINES/18th Connect Workshop held in Dublin on July 15, 2009. The presentation included an overview of the SEASR project. Also in remote attendance were Loretta Auvil and Xavier Llorà of the SEASR Team.

The presentation is available here.

Loretta Auvil, Boris Capitanu, and Amit Kumar of the SEASR Team participate in THATCamp 2009 at George Mason University on June 27-29, 2009. We had the opportunity to have a session on SEASR Analytics. We also had the opportunity to discuss SEASR with many humanities researchers.


A new version (0.3.5) of the SEASR Analytics for Zotero Firefox plugin has been released. The new version adds support for Zotero 1.0.* – 2.0b5 and Firefox 2.0 – 3.5.*. A new set of flows (applications) are available, including: Flesch-Kincaid Readability Test, Tag Cloud Viewer, Date Entities to Simile Timeline, HITS Summarizer, and Author Centrality Analysis.

Our user community wanted a different naming strategy, so that one could tell what items were analyzed. If a single item is selected, then the results item maintains the same name as the item. If multiple items are selected, then the results item uses the collection name followed by the number of items selected. In both cases, the name of the service that is executed is provided in the “Creator” attribute. The selected items are also added to the “Related Items” section – a problem with populating these items was also fixed.

We made several changes to improve configuration file specification. One change includes the ability to specify a configuration file in XML format (json support still exists) with additional error messages to indicate problems with parsing your custom configuration file. This configuration file may exist on your local machine and you can use a file browser to find the local file.
