Knowledge graphs are emerging as a critical layer for AI agents to overcome 'fragmentation' and 'tool explosion' in enterprise settings.

LLM に渡しているのは、しばしば「パズルのピース」だけです。Confluence、Slack、Jira などから取った断片を、その場でつなぎ合わせるしかない設計では、正答率が安定しにくくなります。

The post argues that LLMs often struggle with complex tasks because they are given only 'puzzle pieces' (fragmented data) without a 'box art' (overall context). It proposes using knowledge graphs as a 'partial solution picture' to provide LLMs with structured context, improving accuracy and handling contradictions, especially in multi-agent and team-based AI scenarios.

AI-powered web log analysis reveals hidden, large-scale distributed attacks and scraping that evade traditional detection.

バラバラに見えた約5,000のIPは、1つの分散アクセスだった ― 既知スキャナの再発見から未知を掘り当てる

This post details a method using unsupervised clustering (HDBSCAN + UMAP) on web server logs to identify coordinated distributed access, even when individual IPs have low request volumes. It successfully rediscovered known vulnerability scanners and uncovered a persistent, daily distributed access from ~5,000 IPs across a few hosting providers, which was previously invisible to manual or threshold-based monitoring. The analysis focuses on behavioral features rather than easily faked User-Agent strings.
