Open source library for e-Book log analysis
Project description
OpenLA: open-source library for e-book log analysis
Introduction
OpenLA is an open-source library for e-book log analysis.
This Python library helps reduce redundant development when preprocessing e-book logs: calculating reading times for each learner, counting up operations, page-wise summary of student behavior, etc.
API concept
Four preprocessing processes are essential and common in e-book log analysis: getting course information, converting the log into a form suitable for analysis, extracting the required information, and visualizing the data.
In order to improve efficiency and reduce reiteration in these processes, OpenLA provides the corresponding four modules: Course Information, Data Conversion, Data Extraction, and Data Visualization.
Installation
OpenLA is available on PyPi. You can install it with pip
.
pip install OpenLA
OpenLA works on python 3.7, 3.8, 3.9 and 3.10.
Below are the versions of OpenLA's main dependencies we use for testing, but you probably do not need to worry about this.
- python 3.7: matplotlib 3.5.2, numpy 1.21.6, pandas 1.3.5
- python 3.8 or newer: matplotlib 3.5.2, numpy 1.22.3, pandas 1.4.2
Datasets for OpenLA
The dataset used in this library has the same structure as the open source ones used to conduct Data Challenge Workshops in LAK19 and LAK20.
We target BookRoll logs, but logs from other systems can be adapted.
The dataset may include up to four types of files.
Course_#_EventStream.csv
- Data of the logged activity data from learners' interactions with the BookRoll system
- Columns:
userid
,contentsid
,operationname
,pageno
,marker
,memo_length
,devicecode
, andeventtime
Course_#_LectureMaterial.csv
- Information about the length of the lecture materials used
- Columns:
lecture
,contentsid
, andpages
Course_#_LectureTIme.csv
- Information about the schedule of the lectures
- Columns:
lecture
,starttime
, andendtime
Course_#_QuizScore.csv
- Data on the final score for each student
- Columns:
userid
andscore
Note: from version 0.2.1, OpenLA can treat grading data, which was not present in the LAK19 and LAK20 datasets.
Course_#_GradePoint.csv
- Data on the final grade for each student
- Columns:
userid
andgrade
Where #
is the course id. BookRoll is an e-book system to record learning activities.
