Status and progress update
Progress overview - since last demo
This years version of ABM was released a couple of weeks ago
Recently released beta version of topics based KTH Research Information
Assisting on graphs and summary for KTH Indicator report based on consolidated indicators collected from across KTH.
Tests and prep for GDP 2.0 (Gemensamma dataprojektet) - new standard for Swedish project data
Work to use OpenAlex to update DiVA, and to construct bibliometric database
Annual Bibliometric Monitoring 2025
Changes in ABM 2025
- More interactive graphs (plotly)
- Changed OA graph
- Enabled selection of number of rows for co-publication tables
- Some cosmetic changes
Brief ABM results for KTH
- Number of publications seems to have stabilized
- proceedings have reterned to pre-covid levels
- Tendency for citations indicators to decrease
- will be evaluated further
- seems to be spread across several schools and subjects
- Journal indicators stable but slightly increasing over last 5 years
- Small changes in co-publication patterns
- Share of Open Access publications sharply decreasing last year
- reasons unclear at the moment - might in part be lagging green OA
KTH Research Information - Topics (beta)
- Selection based on Web of Science Citation Topics
- Three levels - macro, meso and micro
- Otherwise similar to KTH Research Information - Units
Swedish bibliometrics & OpenAlex
Background
- Bibliometric analysis has historically been based on commercial data sources (Web of Science, SciVal, Incites, Dimensions)
- Sweden is lacking a national effort or common system
- Latest research bill is pointing towards more openness in research evaluation
OpenAlex
- Open resource, stemming from Microsoft Academic (closed 2021)
- Web interface and API (json)
- Harvesting from Crossref, Pubmed, ArXiv, Zenodo and local repositories
Current status
- Server running on Sunet for snapshot download and data processing
- Flattening of json to .parquet
- Database using duckdb
- Access by database connections and sql requests through basic API
- Model for long-term funding and development currently missing
- Current development with KTHB bibliometrics and the DAUF project, together with KI
Data contents
About 200 mln articles, 24 mln book chapters, 10 mln proceedings

DiVA works in Open Alex
Preliminary/WIP: matching DiVA pid against Open Alex ids using DOIs/PMIDs; coverage:
Future
- Aim for common system and data flows, enabling more transparent and comparable analyses
- Working on project idea with Vinnova, KI and VR
- Evaluation of data
- strengths and weaknesses
- where is additional curation needed?
- More filters for selection of source and work types
- Bibliometric indicators
- Multiple ways for access, depending on different needs and use cases
Data Curation
Data Curation - overview
- Preparations under way for migration to a future new version of DiVA
- Launch of new DiVA with API is postponed, and has new timeline
- All records need review to meet new (not yet finalized) requirements
- Updates are required for KTH curation tools and processes
- Broader discussions relating to a future data lake for “KTH Works”
- Publication data mirrored in a separate system under control from KTH
- Ability to cross reference other research outputs and auxiliary data from external sources
- Revamp curation process - increase automation and data enrichment from external sources, sync to DiVA repository
Data Curation and data flows
Object storage (S3)
- An on-premise data lake is powered by S3 storage using “minio”
- Data is curated and pushed using automated processes to https://data.bibliometrics.lib.kth.se (“minio” / S3)
- Applications and data consumers can then read (and/or write) data there
- See descriptions here for available data
General Dataflow
+--------------------------------+ | | | Data Sources | | | +--------------------------------+ | Clean / Crosscheck / Transform v +--------------------------------+ | | | Curated Data | | | +--------------------------------+ | Write / POST v +--------------------------------+ | | | [S3] Bronze/Silver/Gold | | | +--------------------------------+ | Read / GET v +--------------------------------+ | | | Data Consumer / Client | | | +--------------------------------+
DiVA curation
The DAUF project now harvests DiVA publication data from KTH using the OAI-PMH protocol which regularly updates duckdb databases, openly available from object storage:
- https://data.bibliometrics.lib.kth.se/kthcorpus/oai.db (Raw MODS in XML and JSON)
- https://data.bibliometrics.lib.kth.se/kthcorpus/diva.db (Tables / RDBMs format)
The database is regularly updated. This is WIP and jocularly codenamed “KaTHarsis”
- Harvest of KTH works in DiVA now available as relational database
- Ambition to decouple importing and curation from DiVA in preparation for new DiVA
- Can curate and annotate works using this database, aka “stoplists”
- Preparations to use APIs to sync data between DiVA repository and this database

Curation tools for KTH Works
SQL workbench “Pond Pilot” (wasm) for combining DiVA, OpenAlex and other data sources
GDP
GDP
GDP (Gemensamma data för projekt) is an effort of a number of Swedish research funders to create a common data model for project data. The five funding agencies Energimyndigheten, Formas, Forte, Vetenskapsrådet and Vinnova is developing a standard which enables sharing of open data about fundings and related information.
The standard is developed in cooperation with a reference group including universities and other organisations within the university sector, KTH is a participant in the reference group.
GDP data mobilization
Version 2 of the GDP API has recently been released. Tooling has been developed at KTH for harvesting data from the different sources using this version of the API, see https://github.com/KTH-Library/gdp.
Regular harvesting of data from the API is now available from object storage “minio” at KTH: https://data.bibliometrics.lib.kth.se/projects/gdp/gdp.db
